Modeling and simulation of simple guided mortar using impulse thruster control

The characteristic of body pursuit guidance was introduced. The transfer function of impulse force control was deduced according to the linearization of longitudinal kinetic equations, and the relationship between the different value of impulse force and the miss distance was analyzed. The control algorithm of the impulse force control was designed and simulated based on strapdown laser detector. The affection of the hit precision with different positions of impulse force was analyzed. The simulation results show that the hit precision can be improved greatly by using the gravity compensation with impulse force.
